Abstract: 106,953. Wilputte, L. Dec. 14, 1916. Coke ovens.-In an oven in. which the wall flues are arranged in two groups connected by a common collecting and distributing flue running the length of the heating wall, and in which the direction of flow of the heating gases is reversed at intervals, the means for controlling the distribution of heating gases to the flues of a group are separate from and independent of the means for controlling the delivery and collection of the gases from the flues. As shown in Fig. 15 in connexion with an oven structure having two regenerator chambers running the length of the battery of ovens, two flues U, UA are provided beneath each heating-wall, and are connected on the one hand to the wall flues B by regulable ports W, W<1>, and on the other to a regenerator by passages controlled by dampers X, XA. Gas is supported from a pipe TB through a regulable port. The flues U are traversed by air, and the flues UA by combustion products only, and thus the supply of heating gases to the flues can be controlled independently of the delivery of the gases to the regenerator. In the construction shown in Figs. 1 and 2, the regenerator chambers G run the length of the battery, and are equal in number to the heating flues in a wall. Corresponding wall flues through the battery are connected to the same regenerators, and independent means are provided for controlling the air supply and waste gas exhaust. Each regenerator is divided by transverse perforated walls I corbelled at their upper ends to give strength to the foundations of the ovens, and communicates through passages g with two adjacent flues B in each heating-wall. Air is supplied to the regenerators through pipes M, and the products of combustion are exhausted through ports P into flues N connected by elbow pipes with the main Q<1>. The flues N beneath the regenerators on one side of the oven are preferably connected together by the passages n. The air is delivered from the pipes M through removable laterally-extending nipples, and, to allow the pipe to be removed bodily, the passage in which it fits is formed with radial extensions. Any desired distribution of heating gases in the wall flues can be secured by adjusting the dampers E at the tops of those flues, by changing the nipples on the pipes M, and by varying the size of the ports P leading to the flues N. The gas for combustion is supplied through pipes J in the upper parts of the walls I. The nipples on the pipes M are preferably arranged to supply air to alternate regenerators on each side of a wall I, the remaining chambers beneath any one oven being supplied by the pipe in the opposite wall. With this arrangement, gas of low calorific value can be heated in half of the regenerators, and a system of supply pipes is described by which the oven can be heated either by cold rich gas or preheated poor gas. In a modified construction of oven, the walls 1 are solid so that each wall flue is associated with its own regenerator. In a further modification, each wall flue is subdivided by a vertical partition, and the regenerators are placed in alinement with the wall flues. The flow of gases from the regenerators into the flues N may be controlled by the means shown in Fig. 12 consisting of apertured blocks or plates s mounted in a metal conduit in the flue N and controlling the passage of the gases from the regenerators.
